Hi Mario,

Thanks for posting your example Org file.  Now I am able to reproduce
the problem and know where the bug is.

Just as you said, the problem is caused by the last line that contains
strings "double[9]" and "double[3][3]".  Here "[9]" and "[3]" are
considered footnote references (and I don't think this is what you
wanted), so some code is executed to find the footnote definitions.

The problem happens when the *second* "[3]" is being processed.
Strictly speaking, the second "[3]" is NOT considered as a footnote
reference according to ``org-footnote-re'' (see org-footnote.el), but
some code in org-docbook.el and org-html.el does not use
``org-footnote-re'' and still treats it as a footnote reference.  This
inconsistency caused the problem you saw, and it is only visible in
DocBook exporter.

Before I try to fix the problem, I'd like to get Carsten's confirmation
on the footnote reference syntax: whether the second "[3]", which
immediately follows a character "]", should be treated as a footnote
reference.

To get around this problem, you can try changing the last line to
something like:

  - =double[9]= was less efficient that =double[3][3]=,

Please let me know if you have further questions.
